A. types of pressure exerted by the matter and energy contained in the universe

B. The total mass- energy density of the universe.

C. The rate at which stars rotate: the universe will expand because of centrifugal effect if they rotate sufficiently fast

D.d. The rate of nuclear reactions in the early universe
 
B. The amount of mass-energy that is required to alter the fate of our universe is referred to as "critical density". Critical density is the amount of mass-energy that is required to stop the expansion of the universe. With enough critical density, the gravitational force would be strong enough to reverse the expansion and draw all mass back together in what would be called the "big crunch". Most physicists believe, however, that there is not enough mass for this to happen, even when you take into account the theorized "dark matter." This is because a force, presumably dark energy, is actually accelerating matter away from other matter at apparently faster and faster rates. This more realistic outcome is known as the "flat universe" model.

I would say A because modern physicist have proven that dark energy is the extending force in the universe that is pushing the distance between most galaxies away from each other, with no signs of stopping.(this is why you may hear our universe is growing) which will most likely be the death of the universe.

Also you may want to look up, blue & red shift
